US Route 66

US Route 66 was a 2,448-mile-long US highway which stretches from Chicago, Illinois to Santa Monica, California, running through Missouri, Kansas, Oklahoma, Texas, New Mexico, and Arizona along the way. It was established on 26 November 1926, but, on 26 June 1985, it was removed from the US Highway System after it was replaced in its entirety by segments of the Interstate Highway System. Nevertheless, portions of the road are still known as "Historic Route 66".
